  • Lecture 6 — February 9, 2017 1 Wrapping up on Hashing
    CS 224: Advanced Algorithms Spring 2017 Lecture 6 | February 9, 2017 Prof. Jelani Nelson Scribe: Albert Chalom 1 Wrapping up on hashing Recall from las lecture that we showed that when using hashing with chaining of n items into m C log n bins where m = Θ(n) and hash function h :[ut] ! m that if h is from log log n wise family, then no C log n linked list has size > log log n . 1.1 Using two hash functions Azar, Broder, Karlin, and Upfal '99 [1] then used two hash functions h; g :[u] ! [m] that are fully random. Then ball i is inserted in the least loaded of the 2 bins h(i); g(i), and ties are broken randomly. log log n Theorem: Max load is ≤ log 2 + O(1) with high probability. When using d instead of 2 hash log log n functions we get max load ≤ log d + O(1) with high probability. n 1.2 Breaking n into d slots n V¨ocking '03 [2] then considered breaking our n buckets into d slots, and having d hash functions n h1; h2; :::; hd that hash into their corresponding slot of size d . Then insert(i), loads i in the least loaded of the h(i) bins, and breaks tie by putting i in the left most bin. log log n This improves the performance to Max Load ≤ where 1:618 = φ2 < φ3::: ≤ 2. dφd 1.3 Survey: Mitzenmacher, Richa, Sitaraman [3] Idea: Let Bi denote the number of bins with ≥ i balls.

  • Chapter C4: Heaps and Binomial / Fibonacci Heaps
    Chapter C4: Heaps and Binomial / Fibonacci Heaps C4.1 Heaps A heap is the standard implementation of a priority queue. A min-heap stores values in nodes of a tree such that heap-order property: for each node, its value is smaller than or equal to its children’s So the minimum is on top. (A max-heap can be defined similarly.) The standard heap uses a binary tree. Specifically, it uses a complete binary tree, which we define here to be a binary tree where each level except the last is full, and in the last level nodes are added left to right. Here is an example: 7 24 19 25 56 68 40 29 31 58 Now, any binary tree can be stored in an array using level numbering. The root is in cell 0, cells 1 and cells 2 are for its children, cells 3 through 6 are for its grandchildren, and so on. Note that this means a nice formula: if a node is in cell x,thenitschildren are in 2x+1 and 2x+2. Such storage can be (very) wasteful for a general binary tree; but the definition of complete binary tree means the standard heap is stored in consecutive cells of the array. C4.2 Heap Operations The idea for insertion is to: Add as last leaf, then bubble up value until heap-order property re-established. Insert(v) add v as next leaf while v<parent(v) { swapElements(v,parent(v)) v=parent(v) } One uses a “hole” to reduce data movement. Here is an example of inserting the value 12: 7 7 24 19 12 19 ) 25 56 68 40 25 24 68 40 29 31 58 12 29 31 58 56 The idea for extractMin is to: Replace with value from last leaf, delete last leaf, and bubble down value until heap-order property re-established.

  • Problem Set 2 1 Lazy Binomial Heaps (100 Pts)
    ICS 621: Analysis of Algorithms Fall 2019 Problem Set 2 Prof. Nodari Sitchinava Due: Friday, September 20, 2019 at the start of class You may discuss the problems with your classmates, however you must write up the solutions on your own and list the names of every person with whom you discussed each problem. 1 Lazy Binomial Heaps (100 pts) Being lazy is nothing to be proud of, but occasionally it can improve the overall execution. In this exercise, we will see how delaying the work of the Union operation in the binomial heap can improve the runtime of several operations of the binomial heap. Delete and Decrease-Key operations in the lazy binomial heap will remain unchanged. To implement the new Union we will store the list of roots as a circular doubly-linked list. That is, every node in the linked list has two pointers left and right, including the head and the tail of the list, such that head:left = tail and tail:right = head: We will also maintain the number of elements stored in the heap as a field Q:n (accessible in O(1) time). Consider the following description of Union(Q1;Q2). It simply appends the root list of Q2 to the right of the root list of Q1: function Union(Q1, Q2) if Q1:head = NIL return Q2 else if Q2:head 6= NIL tail1 Q1:head:left; tail2 Q2:head:left . Pointers to the tails of Q1 and Q2 Q2:head:left tail1; tail1:right Q2:head . Link head of Q2 to the right of the tail of Q1 Q1:head:left tail2 ; tail2:right Q1:head .

  • COS 423 Lecture 6 Implicit Heaps Pairing Heaps
    COS 423 Lecture 6 Implicit Heaps Pairing Heaps ©Robert E. Tarjan 2011 Heap (priority queue): contains a set of items x, each with a key k(x) from a totally ordered universe, and associated information. We assume no ties in keys. Basic Operations : make-heap : Return a new, empty heap. insert (x, H): Insert x and its info into heap H. delete-min (H): Delete the item of min key from H. Additional Operations : find-min (H): Return the item of minimum key in H. meld (H1, H2): Combine item-disjoint heaps H1 and H2 into one heap, and return it. decrease -key (x, k, H): Replace the key of item x in heap H by k, which is smaller than the current key of x. delete (x, H): Delete item x from heap H. Assumption : Heaps are item-disjoint. A heap is like a dictionary but no access by key; can only retrieve the item of min key: decrease-ke y( x, k, H) and delete (x, H) are given a pointer to the location of x in heap H Applications : Priority-based scheduling and allocation Discrete event simulation Network optimization: Shortest paths, Minimum spanning trees Lower bound from sorting Can sort n numbers by doing n inserts followed by n delete-min’s . Since sorting by binary comparisons takes Ω(nlg n) comparisons, the amortized time for either insert or delete-min must be Ω(lg n). One can modify any heap implementation to reduce the amortized time for insert to O(1) → delete-min takes Ω(lg n) amortized time.

An ADT is conceptually more abstract than a Java interface specification or C++ list of class member function prototypes, and should be expressed in some formal language (such as mathematics). A data structure is a way of storing data that implements certain operations. When choosing a data structure for your ADT, you might consider many issues such as whether the data is static or dynamic, whether the deletion operation is important, whether the data is ordered, etc. C1.1 Basic Collections There are three basic collections.
